Title: Reverse-run preventer of trolley conveyor carrier
Inventor: KOGA TAKAO
IPC: B61B10/02
Filed: 1995-02-15
Abstract: PURPOSE: To prevent any possible reverse-run due to reaction at the time when a succeeding carrier separated from a driving chain has collided with a stopped preceding carrier from behind, by means of a reverse-run preventer having a reverse-run preventing one-way clutch built in a travel roller of the carrier. CONSTITUTION: A carrier 32 of a trolley conveyor 31 makes a carrier hook 37 engage a pusher dog 36 of a driving chain 35, and it hangs down a conveyed work W and travels. The carrier 32 separated from the driving chain 35 is stopped on the spot, but the succeeding carrier 32 is still engaged with the driving chain 35, so that it canes close to the preceding carrier 32 from behind. Incidentally the succeeding carrier 32 separated from the chain 35 tries to go back owing to reaction at the time of colliding with the stopping preceding carrier 32 from behind. However, since a one-way clutch 50 for checking any reverse-run of a travel roller 43 itself is installed in this roller 43 of the carrier 32, the succeeding carrier 32 is prevented from its reverse-run and thereby it comes to a stop at the very spot where it is separated from the driving chain 35.

Title: Treatment tank for flat plate
Inventor: TOBA RITSUJI
IPC: B05C3/09
Filed: 1979-04-25
Abstract: PURPOSE: To prevent the flapping of a flat plate due to an agitation of liquid by providing guard rails to fix both sides of the flat plate and tools to receive the flat plate in the treatment of the flat plates by dipping in a stirred liquid treatment tank.  
     CONSTITUTION: When placing a flat plate 5 in a treatment tank, the flat plate 5 fixed through a flat plate-fixing tool 6 to a carrier bar 7 is fallen down and then its lower end enters into a V-shaped receiver 1' of the flat plate-receiving tool 1 which slightly projects from the surface of liquid. When it is further fallen down, the flat plate-receiving portion moves down with the flat plate by the weights of the flat plate 5 and the carrier bar 7. When the carrier bar 7 entered into a carrier bar- receiver 8, the flat plate moved down no further. Thus, the flapping of the flat plate can be prevented because the V-shaped receiver 1' of the flat plate-receiving tool touches with the lower end of the flat plate to fit it securely.

Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To enable mechanisms to be kept high in operation timing stability and to operate at a high speed by a method wherein a shutter is driven basing on detection signals outputted from a nozzle proximity sensor. SOLUTION: When a suction nozzle D is kept separate from a prescribed position above a nozzle proximity sensor 40. Light pulses projected from a light projecting part 41 are reflected from the suction nozzle D and then travel rectilinearly toward the front of a photodetector 42, so that light pulses hardly impinge on the photodetector 42. On the contrary, when the suction nozzle D approximates to a prescribed position above the nozzle proximity sensor 40, light pulses projected from the light projecting part 41 are reflected from the suction nozzle D and travel rectilinearly toward the photodetector 42. Therefore, light pulses impinge on the photodetector 42, and the nozzle proximity sensor 40 detects the approach of the suction nozzle D.  When light pulses are detected by the nozzle proximity sensor 40, suction nozzle detection signals are outputted from the nozzle proximity sensor 40, and a shutter 30 starts operating in accordance with the detection signals.
